<span>Basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor</span>

Which best describes a gamete
netineya [11]
A gamete is a haploid cell, a cell with only one pair of chromosomes. Say the skin cell of a human has 46 chromosomes (2 pairs), a gamete would have 23 chromosomes (1 pair) because gametes are sex cells. When a sex cell (Egg and sperm) come together, they together will create a dipole cell (46 chromosomes, 2 pairs).
